This invention relates to folding cartons for display purposes.

It is among the objects to produce from suitably shaped, scored, and slotted cardboard blanks by folding and inter-engagement of parts or fiaps a display container having an opening capable of being opened and closed somewhat in the manner of a roll top desk.

A container thus producible according to this invention requires one foldable blank to represent the carton proper, another blank representing the roll top, and a third blank representing a guide structure insertable into the carton for guiding the sliding movement of the roll top member along a predetermined curved path within the carton.

Some features relate to thecarton blank and mode of folding it. According to one feature the carton blank is such as topresent an upwardly re-v ceding rounded frontwall portion even though folded from a flat blank.

Another feature provides that the display opening is provided by the inward folding of a corresponding flap or tongue and utilizing the inwardly folded fiap as part of a guide structure for the roll top member. More specifically, this feature calls for a secondary fiap or tongue to be struck from the first mentionedfiap which will therefore herein be termed the primary flap or tongue.

Another feature relates to the roll top member, in that it is represented by a blank having horizontal parallel score lines enabling it to adapt itself to changing curvatures along its predetermined slide path within the carton.

Other features relate to the insertable guide structure.

According to one feature this is a U-shaped hollow structure produced from a blank having parallel score lines enabling it to be folded into an elongated hollowbox-shape andslitted transversely so that upright shanks can be struck from each end of a horizontal body portion, thus constituting the U-shape of which the upstanding shank portions form the immediate guide elements for the roll top member. I

More specifically, the slitting of the box-shape is on a bias so that the upright shanks form mitered or pointed corner portions which can be braced against one another by a secondary box-v shaped insert portion slidable into the hollow of the horizontal body portion which hollow is exposed and rendered accessible by reason of the bias slitting. The U-shaped insert portion is 8 Claims. (Cl. 206-44) therefore herein also termed the primary insert portion.

According to another feature the primary insert portion, especially the horizontal body portion thereof serves for receiving and positioning articles, for example cosmetic and perfume bottles, in suitable depressions or sockets.

The invention possesses other objects and features of advantage, some of which with the foregoing will be set forth in the following description. In the following description and in the claims, parts will be identified by specific names for convenience, but they are intended to be as generic in their application to similarparts as the art will permit. In the accompanying drawings there has been illustrated the best embodiment of the invention known to me, but such embodiment is to be regarded as typical only of many possible embodiments, and the invention is not to be limited thereto. v

The novel features considered characteristic of my invention are set forth with particularity in the appended claims. ever, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawings in which Figs. 1 to 4 represent the component blanks with score lines, slits and flaps of the folding display container; Fig, 1 being the blank for the box or carton proper; Fig. 2 being the blank for the roll top member; Fig. 3 being the blank for Fig. 4 being the the primary insert member; blank for the secondary insert member.

'Ilhe, outer'tabs; 83 and 85' as to outline are symmetrical as well as complementary to the tabs I6 and 11 of the bottom portion 66, except for the provision of secondary folding tabs 85 and 81 defined by score lines 08 and 80 respectively. The length of the score line 80 is the same as that of the symmetrical line 16 and represents the basic width W of the tab 86, the height or length of which is indicated by the character I -I. Corresponding dimensions of the tab 81 are indicated by the characters W and H.

The blank 90 in Fig. 4 goes to make up the secondary insert portion (see also Figs. 12, 13, 14 and 15) and comprises a body portion and marginal folding tab portions 92, 93. 94 and 95 defined by score lines 90, 91, 90 and 90.

The blank I00 in Fig. 2 shows the contour of the roll top member defined by a body portion HM and a tab portion I02 which in turn is defined by a pair of notches I03 and H14 constituting a primary constriction and a pair of notches I and I06 constituting a secondary constriction. The contour of the body portion IOI comprises vertical edges I01 and I08, a bottom edge I00, rounded bottom corners H0 and III, and has eXtending across it horizontal score lines H2 evenly spaced from one another. A pair of horizontal score lines H3 and II 4 spaced closely together extend across the tab portion I02 and intermediate the primary and the secondary constrictions as represented by the respective pairs of notches I03, I04 and 105, I06. Another horizontal score line I I5 extends between the notches I05 and I06. Thus the tab I02 has a primary tab portion I02 of reduced width as compared with the body portion WI, and a secondary tab portion I02 of reduced width as compared with the primary tab portion I02 The carton is formed from the Fig. 1 blank by folding on the vertical score lines I2, I3, I4 and I5 so that th glueing tab 20 can be cemented to the inside of panel I9 (see also Fig. 16). The bottom of the carton is formed by folding the tabs 34, 40, 5i and 54 inwardly and interlocking them in the customary manner of carton closure. The top of the carton is formed by folding inwardly along the inclined score lines 45 and 60 as well as along the score lines 44 and 59 respectively to form tapering inward pleats S (see Figs. 11 and 16), and also folding along score lines 43. 20 50 and 51 and interlocking or closing the tabs 42. 49 and 56 asindicated in Figs. 5, 6 and 16.

The display opening M in the front panel iii of the carton becomes effective as such when the upper or primary tab 30 is folded inwardly (as indicated in Figs. 5 and 16) with a break along score lines 30 and 30 that is at the corner 30 (see Fig. 5), thus dividing the tab 30 into a horizontal body-portion 30 and an inclined terminal. portion 30*. The secondary tab 30 remains in line with the horizontal tab portion 30* and lodges in the upper rear corner of the carton and underneath the top cover flaps d2, 49 and 56 when closed. The secondary tab 30 thus also serves as a spacer and for positioning the tab 30 within the upper portion of the carton in a manner whereby it may effectively serve as the upper guide for the roll top member ml.

The underside of the roll top member I00 is confined or guided by the curved top edges H5 and Ill of the upright portions IIS and H9 respectively of a primary insert member I20 from the Fig. 3 blank.

The primary insert member I20 is formed by first folding it on the score lines 68, 69, I2 and 13 into the preliminary shape of the straight hollow box-shaped cpen-ended member shown in Fig. 13 and cementing the tri-sectioned glueing tab II to the corresponding opposite three tab sections I6, I8 and TI (as indicated in Fig. 18 and Fig. 19 in full and dotted lines). Because of the slits I i 14 10 19 and I5 15, 80 in the Fig. 3 blank forming a pair of symmetrical diagonal slits I2! and I22 the end portions of the Fig. 13 member can now be struck upward to constitute the shanks or upright portions H8 and H0 as distinguished from the central or body portion I23 of the primary insert member I20. The body portion I23 of the primary insert member I20 is reinforced by a secondary insert member I24 formed from the Fig. 4 blank 00, the manner of insertion being illustrated in Fig. 14. Fig. 12 also indicates the manner in which the secondary insert member I26 braces the shanks H8 and I I0 against one another so as to help maintain them in upright position as the ends of the box-shaped secondary insert member engage or bias-shaped inner corner portions I25 and I26 of the shanks I I8 and I I9.

The secondary tabs 80 and 8I of the Fig. 3 blank are folded inwardly (see Figs. 13, 14, 15 and 17) at a right angle to their respective primary tabs 83 and 05 to serve as stiffeners and spacers for the tabs 33 and 85 relative to the opposite tabs IE and El. At the top the body portion I23 of the primary insert member I20 is shown to have a pair of larger holes I21 and I28 and a smaller hole I20 interposed between the two larger ones to form receiving sockets for display articles such as the bottles B or vials V shown in Figs. 5, 8 and 9.

The primary insert member I20 and. more particularly the upright shanks H8 and H9 thereof form with the surrounding carton'walls a clearance C (see Fig; 5) within which and along which the roll top member I00 may slide when actuated. by thumb I30 and forefinger I3I (see Fig. 10) grasping a finger tab I32 of the roll top member, Figs. 5, 8 and 10 showing the display window open, while Figs. 9 and 11 show it closed. It will be understood that the finger tab I32 is formed from an integral portion of the roll top member I00, namely by making a complete fold of the portion T1 of the tab I02 (see Fig. 2) on score lines H3, H4, that is by doubling it up so it contacts face to face with the remaining portion T2 of tab I02 and with part of the body portion E0! of the roll top member and then cementing the contacting faces together as at I33 (see Fig. 5). The notches I05 and I06 will then match with notches I03 and, I04 so as to form a single pair of notches in which engage the vertical edge portions I34 and I35 (see Figs. 6, 8 and 9) of the display opening 0 in the front wall of the carton.
